Algebra.Com's Answer #715475 by Boreal(15235)![]() ![]() You can put this solution on YOUR website! -2x - y = 1 \n" ); document.write( "-4x - 2y = -1; multiply the top by -2 \n" ); document.write( "4x+2y=-2; now add \n" ); document.write( "0=-3, the lines are parallel, no solution. \n" ); document.write( "if write in slope intercept form, the first is y=-2x+1 and the second is y=-2x-1/2. The slopes are both -2, parallel lines since the intercepts are different. \n" ); document.write( " |
